PAINT CONTAINER FOR SPRAY APPLIANCES.

Application filed September 21, 1925. Serial N'o. 57,589.

My invention relates to closures for containers, its general object being that of pro-- vidin a container construction which will alfort? a tight closing of the container when l desired and in which the tightly closing cover can istantly be attached. More particularly, my invention provid-es a container comprising a main member and a cover member, these members 4having interfitting 1o projections disposed so as to be engaged or disengaged by a relative rotation of the two members, and provides simple means on the cover member for forcing the latter towards the main container member when the intertting projections are interengaged. More particularly, my invention provides a container proper having a pair of lateral projections near its mouth, a container cover, a thrust member movably mounted on the cover and provided with portions adapted to underhang the said projections, and cam` means for moving the thrust member with respect to the cover so as to force the latter against theJ container. Furthermore, my invention provides a construction for this purpose in which the cam means can be mounted on a single member which connects the thrust member to the cover and which member may be tubular so as to afford an out- 80 let; for the container. Still further and also more detailed objects will ay pear from the following specification and om the accompanying drawings, in which:

ig. 2 is a plan view of the same. Fig. 3 is an enlarged -and fragmentary central and vertical section through theupper portion of Fig. 1, taken along the line 3 3 .of that figure.

Fig. 5 is a fragmentary elevation of the paint cup of Fig. l, taken at right angles to that figure to show the releasable interlocking of the projections on th`e cup wih the ends of the thrust member or yoke carried by the cover.

In constructing paint spraying lappliances of the type in which the atomizer or spray appliance proper' is mounted directly on a cup or otherl container, it has heretoforebeen diiicult to combine a tight sealing of the container with convenience in opening or closing the latter. The liquids used in such appliances usually are of a quick drying nature, so that they will readily gum any threads on both the cup and the cover, thereby making it difficult for the user to detach a cover which is secured to the container in the usual threaded manner. On the other hand,l arrangements heretofore employed for insuring a tight seal between a cup or other container and a slip-on or telescoping cover have usually been both complicated and ditlicult of manipulation. My present invention aims to overcome both of these sets of objections and aims to do so in a quite simple and inexpensive construction. Since my invention in its immediate commercial prospects is particularly applicable for use in connection with paint spraying apparatus, I am illustrating and describing it in a corresponding embodiment, although I do not wish to be limited to any particular use for what` is here disclosed.

In`the embodiments of the drawings, the

lpaint container comprises an upwardly open can or cup 1 carrying a pair of pins 2 which extend diametrically of the can and project from opposite sides of the can at some dis-v tance below the top or mouth end of the latter. The cover 3 'of the lcontainer carries a washer 4 which seats on the upper end of the cup 1, and the cover also has a downwardly directed peripheral flange 5 which telescopes over the mouth end of the can. Extending through a central bore in the cover 3 is a tubular member which has an annular shoulder 6V engaging the top of the cup, and which also has a threaded portion 7 extending through the said perforation, so that the cover can bc clamped against the said shoulder by tightening a Anut 8 which is threaded on the said portion 7 of the tubular member.

The tubular member also has a more elevated cylindrical portion 9 which extends through a corresponding bore in the center of a lyoke or thrust member 10. This yoke reaches beyond the opposite sides of the cover and has a pair of downwardly directed arms 11 each equipped at its lower end with a hook 12 which opens circumferen-A tially ofthe container and which has a portion adapted to vunderhang one of the said pins 2. The yoke l0 is limited as to up- 110 ward movement by engagement with a shoulder 13 on the said tubular member, and the yoke is ada ted to be lifted by a cam member in the orm of a lever 14 threaded on a portion 15 ofthe tubular member above the cover 3, a washer 16 being desirably interposed between the lever 14 and the yoke 10. The lever 14 preferably carries a handle 17 whereby it can be moved rota-tionally about the tubular member, and the threading of the lever on the corresponding part 15 of the tubular member is such that the limited rotational movement permitted by possible engagements ofthe handle 17 `with the yoke 10 will still afford a suflicient lowering or liftin movement to the lever and the yoke for e ecting a clamping or releasing ofthe cover.

When the cover (which consists of the cover proper, the yoke, the tubular member and the cam lever) is detached from the cup or can, the lever is in a lowered position, as for example in that shown in dotted lines in Fig. 2, thereby lowering the yoke so that the latter is out of engagement with the stop 13.

The cover can then be slipped over themouth of the container and the hooks on the yoke can be brought into straddling relation to the pins 2 (as shown in Fig. 5) by a partial rotation of the cover member on the cup. To facilitate this I desirably provide the flange 5 of the cover with a pair of lugs 18 between which one of the depending arms 11 on the yoke extends, so that a rotating of the cover proper will rotate the yoke with it.

After the cover has been vpartially rotated so as to bring the hooks into operative relation to the projecting pins 12, the lever 14 is moved in a direction which is counter-clock- Wise in Fig. 2, namely, the direction in which the thread on the bore 15 causes the lever to move upwardly on the tubular member, thereby also raising the washer 16 and the yoke 10. Since the lower portion of each hook 12 through its engagement with the corresponding pin 2 resists a bodily lifting of the yoke, the result of this lifting action of the lever with respect to the yoke is a depressing of the cover, thereby compressing the packing 4 and insuring a tight closure between the cover and the can. When the container is to be opened, a movement of the lever in the opposite direction releases this pressure, thereby permitting the cover member to be rotated to bring the hooks out of alinement with the pins 2 and then allowing the cover to be lifted bodily.

In employing such a construction in a spraying appliance, the tubular member may have an extension 2O reaching down into the cup 1 to a point near the bottom of the latter, and may have a union nut 21 swiveledon its upper end for making a tight connection to the atomizing or spraying part of the appliance. Thus arranged, the shoulder 6 and the nut 8 cooperate in sealing the tubular member with respect to the cover, and any gumming of the threads 7 will only tighten this seal. On the other hand, the threaded connection between the lcam lever and the tubular member is not reached by the paint or other liquid in the appliance, so that this can not become gummed up. Hence I entirely avoid the difficulties heretofore encountered with containers having covers screwed on their cups, although employing a. quite simple and easily manipulated construction and one in which the needed seal is effected by the compressing of a cheap and easily replaced packing ring.

Since the various connections to the tubular member still permit-this to have an unthreaded bore, this bore is not likely to c log and can easily be cleaned if necessary. So also, the parts attached to the tubular member can easily be removed by merely detaching the nut 8 and then rotating the yoke on the cover. When thus rotated, the yoke engages the handle 17 on the cam lever and rotates the latter also, hence the yoke affords a lever for unscrewing the cam lever, just as it also affords a convenient handle for lifting the cover member when loose or for normally lifting the entire appliance.

However, while I have illustrated and described my invention in an embodiment including highly desirable details of construcmiy tion and arrangements, I do not wish'to be l limited to these, since many changes mi ht obviously be made without departing eit er from the spirit of my invention or from the appended claims.
